Unfounded Call For Taiwan's UN Representation

The recent hype of Taiwan's "meaningful participation" in the UN system by some Western politicians and media organizations echoed related claims made by pro-independence elements in the Chinese island province.

目的 建立家兔氰化钾灌胃给药致死动物模型,研究氰化物代谢物2-氨基噻唑啉-4-羧酸(ATCA)在家兔体内的死后分布规律.方法 雄性家兔7只(体重约2.0kg～2.5kg)经口灌胃2LD50(10mg/kg)氰化钾水溶液,观察家兔反应,待家兔呼吸、心跳和反射全部消失后立即对家兔进行解剖取心、肝、脾、肺、肾、脑、睾丸、胃壁...     

The impact of the Texas top ten percent law on college enrollment: A regression discontinuity approach

We use regression discontinuity methods on a representative survey of Texas high school seniors to discern the impact on flagship‐enrollment behavior of the Texas top 10 percent law, which guarantees admission to any Texas public university to students who graduate in the top decile of their class. By comparing students at and immediately below the cut‐point for automatic admission, we find that the top 10 percent law affects flagship enrollment of Hispanic students eligible for the admission guarantee, as well as rank‐eligible graduates from high schools where minority students predominate and from high schools with the state average share of economically disadvantaged students. Our findings are robust to various model specifications and different bandwidth choices using local linear estimation. © 2010 by the Association for Public Policy Analysis and Management.     

评析小布什政府的新保守主义外交政策的局限性

从"9·11"事件中获得新生的新保守主义对美国外交政策产生了巨大的影响.然而,在国际社会渐趋以非零和博弈和复合相互依存为主要特征的国际背景下,美国新保守主义片面强调意识形态、注重先发制人和单边主义、崇尚武力的进攻性外交政策具有很大的局限性,无法为美国提供全面可靠的指南.     

Photoshop软件在法医临床学鼻面积测量中的应用初探

在鼻部损伤的法医临床学鉴定中,由于鼻的形态不规则,法医学界对鼻部缺损范围的测量和计算尚无一种统一的、精确的方法。本文利用Photoshop软件与传统的薄膜覆盖法分别对鼻面积进行测量,分析两种测量方法所得结果无统计学差异,因此通过软件法可以简便准确的计算鼻部面积。在伤者受伤前与伤后眼裂等器官长度不变的条件下,将伤者眼裂长度作为伤前照片的"比例尺",根据伤前照片推算其伤前鼻部面积,从而计算出鼻缺损比例,为鼻损伤程度的判定提供了更科学的方法。     

以"三个代表"思想为指导进一步开创新世纪民盟工作新局面--学习江泽民同志"七一"重要讲话的体会

江泽民同志在庆祝中国共产党成立80周年大会上的讲话,贯穿始终的灵魂和主题是“三个代表”。《讲话》全面阐述了“三个代表”重要思想的科学内涵,进一步解决了在充满希望和挑战的新的历史条件下,建设一个什么样的党和怎样建设党的问题,是新世纪党的建设的伟大纲领。“三个代表”的重要思想对加强民盟的建设同样具有重要的指导意义。

Global Politics: The Middle East Remains the Darkest Place in 2015

Over the past four years,political changes in the Middle East have always appeared to be unexpected and dazzling.Anti-government"Arab Spring"movements against strongman politics broke out in 2011;political Islam gained power through elections in Tunisia and Egypt in2012;an Egyptian military coup occurred in 2013;and in 2014 the"Islamic State"sprung up in Iraq and Syria.All these seemingly irrational episodes in fact share an inherent logical relationship.Looking ahead to2015,there is no end in sight to the military conflicts currently rife in the Middle East.This includes civil wars such as those in Iraq,Syria,and Libya,and the Yemen and Israeli-Palestinian conflicts.There is no hope for     

固相萃取-气相色谱法检测全血中佐匹克隆

目的采用固相萃取-气相色谱法检测全血中佐匹克隆。方法采用Oasis HLB固相萃取柱对样品进行前处理,去离子水、0.5%氨水-甲醇/水((V/V 40∶60)溶液先后淋洗,二氯甲烷/异丙醇(V/V 75∶25)洗脱后进行GC/NPD检测。结果血液中佐匹克隆在50～5 000ng/mL范围内线性良好(R2=0.998 8),平均萃取回收率为96.9%,检出限为30ng/mL,日内RSD为2.1%～5.7%,日间RSD为3.3%～6.2%,结论固相萃取-气相色谱检测法灵敏度高,重现性好,可在血液中佐匹克隆的检测中选用。
